In this application, cooking utensil has the culinary art runner, and the edible material can be separated into two parts with the culinary art runner in the culinary art runner. The air pressure adjusting assembly in the cooking appliance adjusts the air pressure of at least one side of the food material, so that the food material moves or stops moving under the driving of the air pressure.

Please refer to fig. 1. Fig. 1 is a schematic cross-sectional view of a cooking appliance according to an embodiment of the present invention.

In some embodiments, the cooking appliance includes a cooking body 101, a first air pressure regulating assembly 10.

The cooking body 101 has a cooking flow path 102 extending along a predetermined path. In some embodiments, the cooking flow path 102 is circular in cross-section such that more food material 1 can be contained within the cooking flow path 102. In some embodiments, the cooking flow path 102 may be shaped according to actual conditions. A heater is provided outside the cooking flow path 102 to heat the food 1 in the cooking flow path 102.

After the food material 1 enters the cooking flow passage 102, the cooking flow passage 102 is blocked, and the cooking flow passage 102 is divided into two parts which are not communicated. In some embodiments, the food material 1 is placed in a purpose-made container. The cross-section of the container is the same size as the cross-section of the cooking flow path 102, and the cooking flow path 102 may be divided into two parts. In other embodiments, the food material 1 is itself closing off the cooking flow path 102.

The first air pressure output port 11 of the first air pressure adjusting assembly 10 is communicated or can be communicated with the cooking flow channel 102, and is used for adjusting the air pressure of the cooking flow channel 102 to drive the food material 1 in the cooking flow channel 102 to move or stop moving. How the first air pressure adjusting assembly 10 drives the food material 1 to move or stop moving, so that the food material 1 is selectively located at a predetermined position, and the food material 1 is subjected to a predetermined process. In one embodiment, the food material 1 can be processed in different manners at different positions of the flow passage 102, and the first air pressure adjusting assembly 10 drives the food material 1 to move to different positions for processing in different manners. In another embodiment, during the moving process of the food material 1, the probability that each part in the food material 1 contacts with the side wall of the cooking flow channel 102 is increased, so that the food material 1 can be heated more uniformly.

How the first air pressure regulating assembly 10 drives the food material 1 will be described in detail below.

In some embodiments, the cooking flow path 102 is sealed. The cooking flow path 102 is divided into two parts by the food material 1 in a closed state. The first air pressure output port 11 is communicated with the cooking flow channel 102, and can blow air flow, so that the air pressure of the part where the first air pressure output port 11 is located is increased. Since the air pressure in other portions in the cooking flow path 102 is not changed, the air pressure at the first air pressure outlet 11 is higher than the air pressure in other portions. The larger the gas pressure is, the larger the gas pressure is against the food material 1. The direction of the pressure of the gas on the two sides of the food material 1 to the food material 1 is just opposite. The pressure of the part of the gas at the first gas pressure output port 11 to the food material 1 is greater than the pressure of the other part of the gas to the food material 1, so that the food material 1 moves to a low pressure position.

In some embodiments, the cooking flow path 102 is sealed. The cooking flow path 102 is divided into two parts by the food material 1 in a closed state. The first air pressure output port 11 is communicated with the cooking flow channel 102, and can extract air in the cooking flow channel 102, so that the air pressure at the first air pressure output port 11 is reduced. Since the air pressure in other portions in the cooking flow path 102 is not changed, the air pressure at the first air pressure output port 11 is lower than the air pressure in other portions. The pressure of the part of the gas at the first gas pressure output port 11 to the food material 1 is smaller than that of the other part of the gas to the food material 1, so that the food material 1 moves to a low pressure part. Illustratively, the first air pressure output port 11 is disposed at the end of the cooking flow path 102. The first pneumatic output 11 draws gas. The air pressure at the head end of the cooking flow passage 102 is higher than the air pressure at the tail end of the cooking flow passage 102, the air pressure received by the two sides of the food 1 is different, the pressure at the head end side of the cooking flow passage 102 is higher than the pressure at the tail end side of the cooking flow passage 102, and the food 1 moves to a low pressure part under the driving of the pressure. The more the gas is extracted from the first pneumatic output port 11, the larger the pressure difference formed in the cooking flow path 102, so that the pressure applied to the food 1 moving to the low pressure is increased. The food material 1 can move to the end of the cooking flow path 102 faster under the driving of the pressure.

In some embodiments, the cooking flow path 102 is inclined downwards, and the food 1 can move along a predetermined path under the action of its own gravity. The first air pressure outlet 11 may be provided at the end of the cooking flow path 102. When the food 1 enters the cooking flow passage 102, the food 1 moves toward the end of the cooking flow passage 102 under its own weight. The first air pressure output port 11 blows air flow, so that the air pressure at the end of the cooking flow passage 102 becomes large. The gas pressure on the right side of the food material 1 is greater than that on the left side, and the food material 1 is subjected to the pressure opposite to the moving direction, so that the moving speed of the food material 1 is reduced. Of course, the first air pressure regulating assembly 10 may also adjust the air pressure to increase the flow of air blown in, so that the air pressure at the end of the cooking flow path 102 is changed to be greater. The difference in air pressure between the end of the cooking flow path 102 and the head end of the cooking flow path 102 becomes larger, so that the food material 1 is subjected to a larger pressure. The food material 1 may stop moving or move in a direction of high pressure to low pressure by being driven by the gas pressure.

To enable the cooking flow path 102 to be selectively closed, in some embodiments of the present application, the cooking appliance includes an inlet valve 111 and an outlet valve 112. Wherein, the cooking body 101 has an inlet 107 and an outlet 109 at both ends of the cooking flow path 102, respectively, an inlet valve 111 for opening or closing the inlet 107, and an outlet valve 112 for opening or closing the outlet 109.

In some embodiments, the cooking appliance includes a first container 108 and a second container 110. The first and second containers 108 and 110 are detachably disposed with the cooking body 101. The first container 108 and the second container 110 may be food insulation boxes made of materials with insulation effect, such as plastic, stainless steel, and the like. The size and shape of the first container 108 and the second container 110 may be set according to actual circumstances. The first container 108 can be placed in the first container 108 in advance, the feeding hole 107 is communicated with the first container 108, and the food material 1 in the first container 108 can enter the feeding hole 107 under the action of gravity. The inlet valve 111 and the outlet valve 112 can be controlled manually or automatically. When the inlet valve 111 is opened, the first container 108 is in communication with the cooking flow channel 102, and the food 1 to be heated continuously passes through the inlet 107 from the first container 108 and enters the cooking flow channel 102 under the action of gravity. When the inlet valve 111 is closed, the first container 108 is in a closed state with the cooking flow path 102, and the food item 1 is blocked in the first container 108. When the discharge valve 112 is closed, the discharge port 109 and the second container 110 are in a closed state, and the heated food material 1 is blocked and cannot enter the second container 110 through the discharge port 109. When the discharge valve 112 is opened, the discharge port 109 is in a communication state with the second container 110, and the heated food material 1 enters the second container 110 under the action of gravity. When the food 1 moves in the cooking flow path 102, both the inlet valve 111 and the outlet valve 112 are closed, so that the cooking flow path 102 is in a closed state.

In some embodiments of the present application, a cooking appliance includes a plurality of heating elements. The plurality of heating members are spaced along a predetermined path. The heating modes of the plurality of heating members are different from each other, and are respectively used for heating the food 1 in the cooking flow path 102. The heating member may be an electric heating plate or an IH (Induction Heat) coil plate, an infrared generator, or the like. The heating mode is one of steaming, boiling, frying and other heating modes. In some embodiments, the plurality of heating members are sequentially spaced along the predetermined path, and the food 1 is sequentially heated by different heating modes during the moving process.

In some embodiments, the cooking appliance includes a heating member 121 and a heating member 130. The heating member 121 is a heating wire, is disposed outside the cooking flow passage 102, and is used to heat the cooking body 101, and heats the food material 1 in the cooking flow passage 102 by means of heat conduction. The heating element 130 includes an electrothermal tube and a fan. The electric heating tube heats air inside the cooking main body 101. The fan may heat the food 1 in the cooking flow path 102 by blowing heated air into hot air and forming heat convection to the cooking flow path 102. The heating member 121 heats the food material 1 in a heating mode of cooking. The heating member 130 heats the food material 1 in a frying heating mode.

In some embodiments, the cooking appliance comprises a position sensor 136, the controller 7. The position sensor 136 is used to detect whether the food material 1 exists at a predetermined position of the cooking flow path 102.

In some embodiments, the number of position sensors 136 may be set according to actual needs. If the food material 1 needs to stay at two predetermined positions of the cooking flow path 102, the position sensor 136 may be provided at the predetermined position. The position sensor 136 is disposed at the bottom of the cooking flow path 102, and when the food material 1 passes through the position sensor 136, it can be sensed.

In some embodiments, the cooking flow path 102 is divided into two different sections, each section is provided with a heating element, and the food material 1 is heated in different heating modes. The position sensor 136 may be positioned intermediate the two road segments. When the position sensor 136 senses the food material 1, it indicates that the food material 1 enters another road segment.

The controller 7 is respectively in control connection with the position sensor 136 and the first air pressure adjusting assembly 10, and is used for triggering the adjustment work of the first air pressure adjusting assembly 10 when the position sensor 136 detects that the food material 1 exists.

In some embodiments, the first air pressure regulating assembly 10 is disposed below the throat 107 of the cooking flow path 102. The position sensor 136 is disposed at a predetermined position. For some food materials 1 with poor flowability or large volume, the food material 1 needs to be moved along a predetermined path under the action of the first air pressure adjusting assembly 10. After the food material 1 enters the cooking flow channel 102 from the feeding hole 107, the first air pressure adjusting assembly 10 adjusts the air pressure of the cooking flow channel 102, the food material 1 is pressed to move towards the discharging hole 109, and the food material 1 is driven to move to a preset position to be heated by the heating element. When the position sensor 136 senses the food material 1, it indicates that the food material 1 reaches the predetermined heating position. The controller 7 controls the first air pressure adjusting assembly 10 to stop operating according to the signal sent by the position sensor 136. The pressure in the cooking flow path 102 is the same, and the food 1 cannot move to the discharge port 109. After the food material 1 is heated at the predetermined position, the controller 7 controls the first air pressure adjusting assembly 10 to operate, so that the food material 1 continues to move.

In some embodiments, the position sensor 136 is located downstream of the first air pressure output port 11 of the cooking flow path 102. Specifically, the first air pressure output port 11 blows air into the cooking flow channel 102, so that the air pressure at the first air pressure output port 11 is increased. The food material 1 moves downstream of the first pneumatic output port 11 under the action of the gas pressure. The position sensor 136 is located right on the moving path of the food material 1, and senses the position of the food material 1 driven by the gas pressure.

In some embodiments, the position sensor 136 is located upstream of the first air pressure output port 11 of the cooking flow path 102. At this time, the first air pressure output port 11 extracts the air in the cooking flow channel 102, and the working process of blowing the air flow into the cooking flow channel 102 through the first air pressure output port 11 is just opposite.

In some embodiments, the cooking appliance includes a second air pressure regulating assembly 20. The second air pressure adjusting assembly 20 is in control connection with the controller 7, and a second air pressure output port 21 of the second air pressure adjusting assembly 20 is communicated or can be communicated with a downstream position of the first air pressure output port 11 of the cooking flow channel 102, and is used for adjusting the air pressure of the cooking flow channel 102 to drive the food material 1 in the cooking flow channel 102 to move or stop moving. When the position sensor 136 detects that the food material 1 exists, the first air pressure adjusting assembly 10 is triggered to reduce the air pressure, and the second air pressure adjusting assembly 20 is triggered to increase the air pressure.

In some embodiments, the food material 1 may move along a predetermined path under the influence of its own weight. The first air pressure output port 11 of the first air pressure regulating assembly 10 and the second air pressure output port 21 of the second air pressure regulating assembly 20 both blow air flow into the cooking flow channel 102. The cooking flow path 102 is divided into two closed portions by the food material 1. The first pneumatic output port 11 is located near the feed port 107 of the cooking flow path 102, and the second pneumatic output port 21 is located near the discharge port 109 of the cooking flow path 102. When the first air pressure output port 11 blows in air flow, the air pressure of the part where the feed inlet 107 is located is increased, and then the food material 1 moves towards the discharge outlet 109 under the driving of the self gravity and the air pressure. When eating material 1 and arrive predetermined position, by the back that position sensor 136 sensed, first atmospheric pressure adjusting part 10 reduces atmospheric pressure for eat the gas pressure that material 1 received and remove to discharge gate 109 and no longer drive and eat material 1 and remove to discharge gate 109. The food material 1 will continue to move away from the predetermined position under the action of its own gravity. In order to make the food material 1 stay at the predetermined position, the second air pressure output port 21 blows air flow, so that the air pressure of the part of the cooking flow channel 102 where the discharge port 109 is located is increased. The air pressure at the outlet 109 of the cooking channel 102 is greater than the air pressure at the inlet 107, so that the pressure of the gas moving to the inlet 107 on the food material 1 is greater than the pressure of the gas moving to the outlet 109. The gas pressure driving the food material 1 to move toward the feed opening 107 is balanced with the gravity of the food material 1 itself so that the food material 1 can stay at a predetermined position.

In some embodiments of the present application, the cooking appliance includes a first pressure sensor 12, a second pressure sensor 22. The first pressure sensor 12 is connected to the controller 7 and is located at a position upstream of the position sensor 136 of the cooking flow path 102 for detecting the air pressure in the cooking flow path 102 under the action of the first air pressure regulating assembly 10. The second pressure sensor 22 is connected to the controller 7 and is located at a position downstream of the position sensor 136 of the cooking flow path 102 for detecting the air pressure in the cooking flow path 102 under the action of the second air pressure adjusting assembly 20.

In some embodiments, the first pressure sensor 12 is the same kind as the second pressure sensor 22. The first air pressure output port 11 is located near the throat 107, and the first pressure sensor 12 senses the air pressure in the cooking flow path 102 near the throat 107. The second air pressure output port 21 is located near the discharge port 109, and the second pressure sensor 22 senses the air pressure in the cooking flow channel 102 near the discharge port 109. When the first air pressure adjusting assembly 10 and the second air pressure adjusting assembly 20 can be operated simultaneously, the first pressure sensor 12 can sense the air pressure in the cooking flow channel 102 in real time. The second pressure sensor 22 is capable of sensing the air pressure within the cooking flow path 102 in real time.

The controller 7, in response to the position sensor 136 detecting that there is a food material 1, controls the first air pressure regulating assembly 10 to regulate and operate so as to reduce the air pressure in the cooking flow channel 102 under the action thereof until the air pressure detected by the first pressure sensor 12 reaches a first predetermined air pressure value, and simultaneously controls the second air pressure regulating assembly 20 to start operating so as to increase the air pressure in the cooking flow channel 102 under the action thereof until the air pressure detected by the second pressure sensor 22 reaches the first predetermined air pressure value. In some embodiments, the first predetermined air pressure value may be automatically adjusted according to the food material 1, so that the food material 1 stays at the predetermined position and does not move continuously.

In some embodiments, the food material 1 will move along the predetermined path of the cooking flow path 102 due to the gravity of the food material 1 itself. After the position sensor 136 detects that the food material 1 exists, the controller 7 controls the first air pressure adjusting assembly 10 to adjust, so as to reduce the blown air flow and reduce the air pressure value. The controller 7 controls the second air pressure adjusting assembly 20 to adjust and work, increase the blown air flow and increase the air pressure value. The value of the air pressure sensed by the first pressure sensor 12 is less than the value of the air pressure sensed by the second pressure sensor 22. The gas pressure at the discharge port 109 is greater than the gas pressure at the feed port 107, and the gas pressure for driving the food material 1 to move toward the feed port 107 is balanced with the gravity of the food material 1 itself, so that the food material 1 stays at a predetermined position.

In some embodiments, the controller 7 controls the first air pressure adjusting assembly 10 to adjust the operation thereof so that the air pressure in the cooking airflow channel 102 under the operation thereof increases from the first predetermined air pressure value to the second predetermined air pressure value in response to the predetermined condition being met, and controls the second air pressure adjusting assembly 20 to adjust the operation thereof so that the air pressure in the cooking airflow channel 102 under the operation thereof decreases from the first predetermined air pressure value to the third predetermined air pressure value. The predetermined condition is, for example, that a preset time period has elapsed, and that the food 1 has undergone a predetermined cooking process. After the predetermined condition is satisfied, one side of the food material 1 is a second predetermined air pressure value, and the other side is a third predetermined air pressure value lower than the second predetermined air pressure value, so that the food material 1 is pushed to shift the position. Specifically, the food 1 is pushed to move to another position to continue the cooking process, or the food 1 is pushed to the outlet.

In some embodiments, the first air pressure regulating assembly 10 is used to output an air flow from the first air pressure output port 11. Wherein, the cooking main body 101 has a first air inlet (not labeled) communicated with the cooking flow passage 102. The first air pressure output port 11 is communicated with the first air inlet to blow air flow into the cooking flow channel 102, thereby increasing the air pressure in the cooking flow channel 102.

In some embodiments, the air flow output by the first air pressure output port 11 is a hot air flow. The first air pressure output port 11 outputs air flow to raise the air pressure in the cooking flow path 102. The air flow heats the food material 1 in the process of flowing from high pressure to low pressure, so that the food material 1 can be heated more quickly.

In some embodiments, the second air pressure regulating assembly 20 is used to output an air flow from the second air pressure output port 21. Wherein the cooking body 101 has a second air inlet (not shown) communicating with the cooking flow passage 102. The second air pressure output port 21 is communicated with the second air inlet port to blow air flow into the cooking flow channel 102, thereby increasing the air pressure in the cooking flow channel 102. Similarly, the air flow output from the second air pressure output port 21 is also a hot air flow.

In some embodiments, the first air pressure adjusting component 10 is a blower, and an air outlet of the blower forms the first air pressure output port 11. Specifically, an air inlet of the blower is communicated with the first air inlet, and the blower forms air flow into the cooking flow channel 102. The power of the fan is adjustable. When the power of the fan is increased, the gas flowing into the cooking flow path 102 increases, and the gas pressure in the cooking flow path 102 increases. When the power of the fan is turned down, the gas flowing into the cooking flow path 102 becomes less, and the gas pressure in the cooking flow path 102 decreases.

In some embodiments, the second air pressure regulating assembly 20 is the same as the first air pressure regulating assembly 10 and is a fan. The air outlet of the fan forms a second air pressure output port 21.

Please refer to fig. 1 and fig. 2. Fig. 2 is a schematic cooking flow diagram of an embodiment of the cooking appliance of the present application.

S101: the food material 1 is inserted into a cooking flow path 102 of the cooking main body 101 extending along a predetermined path.

In some embodiments, the cooking appliance has a cooking body 101 and a first container 108. The cooking body 101 has a cooking flow path 102 extending along a predetermined path. The food material 1 moves along a predetermined path in the cooking flow path 102. The first container 108 is a plastic box. The first container 108 communicates with the feed opening 107 of the cooking flow path 102. Food material 1 may be placed first in the first container 108. When the inlet valve 111 is open, the foodstuff 1 enters the cooking flow channel 102 under the influence of gravity, dividing the cooking flow channel 102 into two parts.

S102: the air pressure of the cooking flow channel 102 is adjusted to drive the food 1 in the cooking flow channel 102 to move.

In some embodiments, the food material 1 has poor fluidity or large volume and cannot move in the cooking flow channel 102 under the action of its own weight. Specifically, by adjusting the gas pressure in the cooking flow channel 102, the gas pressure on both sides of the food material 1 is different, so that the food material 1 is driven to move by the larger gas pressure.

In some embodiments, the step of adjusting the air pressure of the cooking flow channel 102 to drive the food 1 in the cooking flow channel 102 to move comprises the following steps:

s103: it is detected whether the food material 1 is present at a predetermined position of the cooking flow path 102.

In some embodiments, the cooking appliance includes a position sensor 136. The position sensor 136 is disposed in the cooking flow channel 102 for sensing the position of the food material 1 in the cooking flow channel 102. There may be a plurality of predetermined positions of the cooking flow path 102, and different predetermined positions heat the food material 1 in different heating modes. The position sensor 136 is arranged at a predetermined position, and when the food material 1 is sensed by the position sensor 136, it means that the food material 1 reaches the predetermined position.

S104: in response to the position sensor 136 detecting the presence of the food item 1, the air pressure of the cooking flow channel 102 is adjusted to drive the food item 1 within the cooking flow channel 102 to stop moving.

In some embodiments, the air pressure in the cooking flow path 102 is adjusted by the first and second air pressure adjusting assemblies 10 and 20. The first air pressure adjusting assembly 10 is disposed at the feeding hole 107 of the cooking flow channel 102, and outputs air flow into the cooking flow channel 102 through the first air pressure output port 11 to increase the air pressure in the cooking flow channel 102. The second air pressure adjusting assembly 20 is disposed at the discharge port 109 of the cooking flow channel 102, and outputs air flow into the cooking flow channel 102 through the second air pressure output port 21, so as to increase the air pressure in the cooking flow channel 102. The first air pressure regulating assembly 10 and the second air pressure regulating assembly 20 are both fans. After the food material 1 enters the cooking flow channel 102 from the feeding hole 107, the first air pressure adjusting assembly 10 operates to blow air flow. The second air pressure regulating assembly 20 stops operating. The air pressure at the inlet 107 of the cooking channel 102 is greater than the air pressure at the outlet 109, and the food material 1 moves toward the outlet 109 under the driving of the greater air pressure. When the position sensor 136 senses the food material 1, the air flow blown by the first air pressure regulating assembly 10 is reduced, so that the air pressure at the feeding port 107 of the cooking flow channel 102 is reduced. The second air pressure adjusting assembly 20 works to increase the air pressure at the outlet 109 until the air pressure at the inlet 107 and the outlet 109 of the cooking flow channel 102 are the same. Since the gas pressures at the inlet 107 and the outlet 109 of the cooking flow path 102 are the same, the gas pressures at both sides of the food material 1 are equal, and the food material 1 stays at a predetermined position.

Please refer to fig. 1 and fig. 3. Fig. 3 is a schematic cooking flow diagram of an embodiment of a cooking appliance according to the present application.

S201: cooking is started.

The cooking utensil is provided with a control panel (not shown in the figure), and a user can select to start cooking at regular time or directly start cooking.

S202: the food enters the cooking flow path 102.

The inlet valve 111 is opened and the food 1 flows from the first container 108 into the cooking flow path 102 under the influence of gravity. The food material 1 divides the cooking flow path 102 into two parts.

S203: the first air pressure regulating assembly 10 operates.

The first air pressure regulating assembly 10 has a first air pressure output port 11. The first air pressure output port 11 is disposed near the feeding inlet 107, and blows air into the cooking flow channel 102, so that the air pressure at the feeding inlet 107 of the cooking flow channel 102 is increased. The air pressure at both sides of the food material 1 is different, so that the food material 1 moves under a larger air pressure.

S204: it is determined whether the first pressure sensor 12 detects that the pressure has reached P1.

The first pressure sensor 12 may detect the air pressure in the cooking flow path 102 in real time. The size of P1 can be adjusted according to the food material 1. When the fluidity of the food material 1 is good, P1 is lowered, and the food material 1 can be driven to move by a smaller gas pressure. When the fluidity of the material 1 is good, P1 is increased, and the material 1 is driven to move by a larger gas pressure. If the first pressure sensor 12 detects that the pressure reaches P1, the flow proceeds to step S205. If the first pressure sensor 12 detects that the pressure does not reach P1, it returns to step S203.

S205: it is determined whether the food material 1 reaches a predetermined position.

The cooking flow path 102 has a first cooking chamber 102a and a second cooking chamber 102b. The position sensor 136 is disposed in the middle of the first and second cooking chambers 102a and 102b. When the position sensor 136 senses the food material 1 for the first time, it means that the food material 1 passes through the first cooking chamber 102a and enters the second cooking chamber 102b, and reaches the predetermined position. When the food material 1 reaches the predetermined position, the process proceeds to step S206. If the position sensor 136 does not detect the food material 1, it indicates that the food material 1 does not reach the predetermined position, and the process returns to step S203.

S206: the second air pressure regulating assembly 20 is operated, the pressure detected by the second pressure sensor 22 and the pressure detected by the first pressure sensor 12 are both P2, and P2 is smaller than P1.

The predetermined position is the second cooking chamber 102b. After the food material 1 reaches the predetermined position, the second air pressure adjusting assembly 20 operates, and the air pressure near the discharge port 109 increases. The first air pressure regulating assembly 10 reduces the flow of the blown air and the air pressure in the vicinity of the feed opening 107 decreases. When the gas pressure near the outlet 109 is increased to P2 and the gas pressure near the inlet 107 is decreased from P1 to P2, the gas pressures at the inlet 107 and the outlet 109 are equal. The gas pressure on both sides of the food material 1 is equal and the food material 1 stays in the second cooking chamber 102b.

S207: the heating of the food material 1 is completed at a predetermined position.

Specifically, the heating member 121 is annularly provided to the second cooking chamber 102b. The food material 1 is heated in the second cooking chamber 102b in a heating mode of cooking. The second cooking chamber 102b has a temperature sensor 137 therein, which indicates that the heating of the food material 1 is completed when the food material 1 is heated to a predetermined temperature.

S208: the first air pressure regulating assembly 10 stops operating, the second air pressure regulating assembly 20 continues operating, and the pressure sensed by the second pressure sensor 22 is P1.

After the food 1 is heated in the second cooking cavity 102b, it needs to move to the next predetermined position for heating. The next predetermined position is the first cooking chamber 102a. Since the first cooking chamber 102a is upstream of the second cooking chamber 102b, the first air pressure adjusting assembly 10 stops operating, so that the air pressure at the feed opening 107 of the cooking flow path 102 is reduced. The second pressure regulating assembly continues to work, and the air flow output by the second air pressure output port 21 is increased, so that the air pressure sensed by the second pressure sensor 22 is P1. The gas pressure at the right side of the food material 1 is greater than the gas pressure at the left side of the food material 1, thereby driving the food material 1 to flow toward the first cooking chamber 102a.

S209: it is determined whether the food material 1 reaches the next predetermined position.

Since the position sensor 136 is located between the first cooking chamber 102a and the second cooking chamber 102b, the food 1 moves from the outlet 109 toward the inlet 107. Food 1 passes the position sensor 136, indicating that food 1 is moving from the second cooking chamber 102b to the first cooking chamber 102a. If the food material 1 reaches the next predetermined position, the process proceeds to step S210. If the food material 1 does not reach the next predetermined position, step S208 is entered.

S210: the pressure detected by the second pressure sensor 22 and the pressure detected by the first air pressure sensor are both P2.

The second air pressure regulating assembly 20 reduces the flow of air blown in and the air pressure near the discharge port 109 decreases. The first air pressure regulating assembly 10 is operated and the air pressure near the feed port 107 is raised to P2. After the gas pressure near the discharge port 109 is decreased from P1 to P2, the gas pressures at the feed port 107 and the discharge port 109 are equal. The gas pressure on both sides of the food material 1 is equal and the food material 1 stays in the first cooking chamber 102a.

S211: the heating of the food material 1 is completed at a predetermined position.

Specifically, the heating member 130 is disposed at the first cooking chamber 102a. The food material 1 is heated in the first cooking chamber 102a in a frying heating mode. The first cooking chamber 102a has a temperature sensor 135 therein, which indicates that the heating of the food material 1 is completed when the food material 1 is heated to a predetermined temperature.

S212: the first air pressure regulating assembly 10 is operated, the second air pressure regulating assembly 20 is stopped, and the first pressure sensor 12 senses the air pressure P1.

After the food material 1 is heated, the first air pressure adjusting assembly 10 operates, so that the air pressure at the feeding port 107 is P1. The second air pressure regulating assembly 20 stops working and the air pressure at the discharge port 109 is reduced. The gas pressure on the left side of the food material 1 is greater than the gas pressure on the right side of the food material 1, so that the food material 1 is driven to move to the discharge hole 109.

S213: the food material 1 falls into the second container 110.

The discharge valve 112 is opened and the food material 1 falls into the second container 110 under the influence of gravity. The second container 110 is a food warming box.

S214: and (6) finishing cooking.

After the food material 1 is cooked, the cooking appliance can automatically preserve heat for the food material 1. Specifically, the second nozzle 133 outputs high-temperature gas into the second container 110 to keep the temperature of the food material 1.

In some embodiments, the cooking appliance includes a cooking body 101, a heating member, a first air pressure regulating assembly 10, a second air pressure regulating assembly 20, a position sensor 136, a controller 7, a first pressure sensor 12, a second pressure sensor 22, an inlet valve 111, an outlet valve 112, a first container 108, a second container 110.

The cooking body 101 has a cooking flow path 102 extending along a predetermined path. The cooking flow passage 102 has an inlet 107 and an outlet 109 at its opposite ends. The cooking flow path 102 has a first cooking chamber 102a and a second cooking chamber 102b. The food material 1 is heated in the first cooking chamber 102a in a frying heating mode. The food 1 is heated in the second cooking chamber 102b in a frying heating mode. The cooking body 101 also has a liquid inlet 119 and a liquid outlet 120. After the cooking appliance finishes heating the food material 1, the cleaning liquid flows into the liquid inlet 119 to clean the cooking flow channel 102. After the washing is completed, the cleaning liquid flows out from the liquid outlet 120.

The heating members are two, a heating member 121 and a heating member 130. The heating element 121 is an electric heating wire, and is disposed around the corresponding cooking flow channel 102 of the second cooking cavity 102b. The heating element 130 includes an electrothermal tube and a fan (not shown). The electric heating tube heats air inside the cooking main body 101. The fan may heat the food 1 in the cooking flow path 102 by blowing the heated air into hot air toward the cooking flow path 102 and forming thermal convection. The heating member 130 is disposed at the top of the first cooking chamber 102a, and heats the food material 1 in the first cooking chamber 102a in a frying heating mode. A heating member 121 is further provided at the bottom of the first cooking chamber 102a so that both the top and the bottom of the food material 1 can be heated.

The first and second containers 108 and 110 are detachably disposed with the cooking body 101. The first container 108 is a food box, and the unheated food material 1 is placed in the first container 108. The feed opening 107 is communicated with the first container 108, and the food material 1 in the first container 108 can enter the feed opening 107 under the action of gravity. The second container 110 is a food heat-preserving box, and the heated food material 1 can be heat-preserved for a long time after entering the second container 110.

The first air pressure adjusting assembly 10 has a first air pressure output port 11 disposed near the feed port 107. The first air pressure output port 11 blows air flow into the cooking flow passage 102 for adjusting the air pressure in the cooking flow passage 102. The second air pressure adjusting assembly 20 has a second air pressure output port 21 disposed near the discharge port 109 for adjusting the air pressure in the cooking flow channel 102. The first air pressure regulating assembly 10 and the second air pressure regulating assembly 20 are both fans.

The position sensor 136 is disposed between the first and second cooking chambers 102a and 102b. When the position sensor 136 senses food item 1, it indicates that food item 1 enters the second cooking cavity 102b from the first cooking cavity 102a.

The first pressure sensor 12 is disposed near the first air pressure output port 11, and is configured to sense an air pressure in the cooking flow channel 102 after the first air pressure adjusting assembly 10 operates. The second pressure sensor 22 is disposed near the second air pressure output port 21, and is configured to sense the air pressure in the cooking flow channel 102 after the second air pressure adjusting assembly 20 works.

The inlet valve 111 is disposed at the inlet 107, and is used for controlling the opening and closing of the inlet 107. The discharge valve 112 is provided in the discharge port 109, and controls opening and closing of the discharge port 109.

The controller 7 is in control connection with each sensor, and controls the first air pressure regulating assembly 10 and the second air pressure regulating assembly 20 to adjust according to signals of each sensor.

The working process is as follows:

the user selects to cook the food material 1 with water and then fry the food material through the control panel of the cooking appliance. After the cooking mode is selected, cooking is started.

The inlet valve 111 is opened and food 1 enters the first cooking chamber 102a of the cooking flow path 102 from the first container 108. The first air pressure regulating assembly 10 is operated and the first air pressure outlet 11 blows air, so that the air pressure at the feed inlet 107 of the cooking flow channel 102 is increased. After the first pressure sensor 12 senses that the air pressure reaches P1, the first pressure regulating assembly 10 maintains power, so that the air pressure at the feeding port 107 maintains P1. The gas pressure at the discharge port 109 is lower than the gas pressure at the feed port 107, and the food material 1 is driven by the larger gas pressure to move from the feed port 107 to the discharge port 109.

The food material 1 is moved in the direction of action of the atmospheric pressure by the gas pressure. The food 1 passes the position sensor 136 and reaches the second cooking chamber 102b. The controller 7 adjusts the first pressure regulating assembly 10 to decrease the pressure at the feed port 107 such that the pressure sensed by the first pressure sensor 12 is P2. The second air pressure regulating assembly 20 operates to increase the air pressure at the outlet 109 so that the pressure sensed by the second pressure sensor 22 is also P2. The gas pressure at the inlet 107 and outlet 109 are equal. The gas pressure on the left and right sides of the food material 1 is the same, and the food material 1 stays in the second cooking cavity 102b. The heating member 121 operates to heat the food material 1 in a cooking manner.

After the temperature sensor 137 in the second cooking cavity 102b senses that the food material 1 is heated to the predetermined temperature, the controller 7 adjusts the first and second air pressure adjusting assemblies 10 and 20, so that the food material 1 moves to the first cooking cavity 102a. Specifically, the first air pressure adjusting assembly 10 stops operating, and the air pressure at the feed port 107 is reduced to the initial air pressure. The second air pressure regulating assembly 20 continues to operate and increases the flow of air blown in so that the air pressure at the outlet 109 reaches P1. The gas pressure at the right side of the food material 1 is higher than that at the left side, and the food material 1 moves towards the feed inlet 107 under the drive of the higher gas pressure. The food 1 again passes the position sensor 136 and moves from the second cooking chamber 102b to the first cooking chamber 102a. Likewise, to make the food material 1 stay in the first cooking cavity 102a, the controller 7 adjusts the first and second air pressure adjusting assemblies 10 and 20 so that the air pressures at the feeding inlet 107 and the discharging outlet 109 are P2. The heating member 121 and the heating member 130 of the first cooking chamber 102a are operated, and the food 1 is heated in a fried manner in the first cooking chamber 102a.

After the temperature sensor 135 in the first cooking cavity 102a senses that the food material 1 is heated to a predetermined temperature, the controller 7 adjusts the first and second air pressure adjusting assemblies 10 and 20. The gas pressure at the inlet 107 is increased to P1 and the gas pressure at the outlet 109 is decreased to the initial gas pressure. The gas pressure on the left side of the food material 1 is greater than the gas pressure on the right side, and the food material 1 is driven by the greater gas pressure to move towards the discharge hole 109. The discharge valve 112 is opened and the food material 1 falls into the second container 110 under the influence of gravity.

The cooking body 101 includes a first nozzle 131 and a second nozzle 133. Specifically, the first nozzle 131 blows high-temperature water vapor into the first cooking chamber 102a, so that the food 1 is heated by the vapor in the first cooking chamber 102a. The user can steam-heat the food material 1 as desired.

After the food material 1 enters the second container 110, the cooking appliance enters a keep warm mode. The second nozzle 133 outputs high-temperature steam into the second container 110 periodically to keep the food 1 warm.

Specifically, the above description is only an embodiment of the present application, and not intended to limit the scope of the present application, and all equivalent structures or equivalent processes that are transformed by using the content of the present specification and the attached drawings, or directly or indirectly applied to other related technical fields are also included in the scope of the present application.
